Feelings of hunger are decreased by high levels of PYY and decreased by high levels of leptin.
Extra: Hunger and satiety signals in the body are controlled by a complex interplay of hormones and brain signals. Two of these hormones are PYY and leptin.
PYY, or peptide YY, is a hormone that is released by cells in the small intestine and colon in response to eating. High levels of PYY are released after you eat, which then travel through the bloodstream to the brain. PYY binds to receptors in the hypothalamus, which is the part of the brain that regulates appetite. When PYY attaches to these receptors, it sends a signal that you are full, which decreases appetite and helps to reduce food intake.
